Hundreds Chart

Does this look a little different to hundreds charts that you are used to?

There are a few reasons why our typical hundreds charts (starting at 1 and working the way down to 100) need updating.

First question . . . why does the chart start from the highest number, you ask? The answer to this question is quite simple. How do you count..up! So in actuality, the chart starts at the bottom at zero and we count up to 100+.

Second question . . . zero, don't we start at one?!? Our hundreds chart and number lines should always start at zero. Take a look at the patterns that can be identified by simply adding the zero. Ten numbers can be found in each group of tens which makes this an excellent tool for "adding ten" strategies. Adding the zero to your hundreds chart can also do wonders for teaching the concept of place value.

Here are some links to additional information on adding the zero onto your hundreds chart:
